TypeScript 5.3.3 (#4464external link)
anchor

We have upgraded TypeScript to version 5.3.3. At this point we cannot go any higher because of the @rmwc/* packages.

Also, fastify was updated to 4.29.0 - which might affect users which are hooking into the fastify handler. If something is wrong in your code, the TypeScript build will break, and it is an easy fix - just check the fastify docsexternal link.
